Hospital Clinic of Barcelona·interventional·Posted May 21, 2009·Updated Mar 18, 2025

In Brief

A clinical study evaluating Immunochemical fecal occult blood test and Colonoscopy for Colorectal Cancer and Colorectal Neoplasm. Completed, enrolled 55,498 participants across 8 sites.

Detailed Summary

Aims: 1. To compare the efficacy of biennial immunochemical fecal occult blood test (iFOBT) versus colonoscopy every 10 years for the reduction of colorectal cancer-related mortality at 10 years in average-risk population. 2. To determine the compliance and complications associated with both strategies. Methods: Multicenter, randomized, controlled study in 8 Spanish regions (Aragón, Canarias, Catalunya, Euskadi, Galicia, Madrid, Murcia and Valencia). Study groups: * Group I: iFOBT (OC Sensor®) in one stool sample, followed by colonoscopy when a positive result. * Group II: colonoscopy. Sample-size calculation: 27,749 subjects in each study group (total: 55,498).
